It is a F12 fan and blowing down. When it is stacked that way it will draw air over back of board above. Equally setting a stack heigh of say 40mm would allow reasonable side to side air flow especially if the ends are boxed as well. We are looking for a r/a bracket that will allow the side mount fans for the push pull fan arrangement but that is not high priority at the moment.

The F12 is a very quite fan with good airflow and long life. The way we did the mounts will also allow a heatsink and fan arrangement for the back if you want but that is

Oh no! Yohan was taken by ninjas midway through his post! Now we may never hear more about the rear mount cooling stuff! I bet Bitcoin Kitteh was in on it!

Yohan,

There is one very important statistic that hasn't been posted yet.  I understand that anything at this point would be only an educated guess since the bitstream isn't built yet, but that's all I'm looking for at this point is a rough estimate.  Can you get a number from the engineers on what the cat-hair/Mh is going to be?  Are we talking 0.01, 1, 100?

They haven't posted yet admittedly, mostly since they've not done full tests to be able to go around boasting yet.
However this type of processor is capable of 200 Mhash/s each, it was used in the Icarus Board (twin processor).
There is 4 of them, thus 800+ is the minimum to be expected really.

With the right modifications, tweaks and fairy dust (kidding about that last one), many have suggested it is possible to push each processor to do 250 each. So a ballpark figure of 800-1000 Mhash/s is the only news on it right now.

Concerning cat hair. It has a fan guard but no filter, so keep fluffy away from it Smiley

It would be nice to roll eldentyrell's bitstream onto these boards and get close to that 1GH output.

apparently we'll know what's going to happen w/ that in this many days

I think thats just his way of buying MORE time.

Like eldentyrell said in his thread, hes always coming up with new and interesting ways to say its going to be a bit longer ...

Update Time

Ok the machines have started and the first Issue 1.1 boards came of the line on Friday. We have been doing basic testing on them and doing work on our Controller design. That basic testing is now complete and our line has been given the green light to continue with the rest of this week's planned build of 50 boards.

We have now started to look at the bitstream solution and software interface. We are going to try and complete this within a few days but as it is a development there is always a chance of a problem. However during these few days we are looking to ship a few boards to developers of bitsreams/software and anyone that feels that they are in that category, and have not already flagged that to our sale team, should do so if they want a very early board. Early access developers should be happy to programming FPGAs with programming cables as that will be the way for at least a few days to program these boards. I am expecting the first boards to ship on Friday/Monday to Developers.

We are now in a good position on component supplies and we will be looking at the finer detail of the schedule in about 1-2 weeks time when we have a clearer view of how the assembly and test lines cope with the new board. We should start updating you all on when your boards are likely to arrive.

Our order book for July is nearly full and I expect that to close before Friday and we will quote September or later thereafter. There is a possibility of pulling some time back but we won't make any promises at this stage. We are not promising anything production wise for August currently as it is a major UK holiday time and our production levels will be substantially lower. However there is likely to be some August production but we need to do a proper calculation of the holiday effect and that will take some time to do. Some staff have not booked holidays yet and that is a moving effect as well that we are not certain of as yet. I may revise this delivery advice once we see how the lines cope with the Cairnsmore1 in numbers but that is a bedding in and learning process that we still have to do.

Generally we are meeting our aggressive design and production start up schedule and I hope everyone is happy on that. It is a bit rough and ready at the moment but I did say it was likely to be that way at the beginning less than 5 weeks ago when we announced the board concept and that will improve over the coming few weeks.

Email response times will be slow on the 24th May as we are running a major training event in conjunction with our partners on our general product lines.

We should start asking some of you for your initial payments late this week or early next.

I would highly recommend getting in contact with this group here. It is not clear from what I've read if they have a bitstream available but they appear to be onto something with the formula of many smaller rounds versus the fit as many big rounds as one can on the chip..

cheers

If you're not excited by the idea of being an early adopter 'now', then you should come back in three or four years and either tell us "Told you it'd never work!" or join what should, by then, be a much more stable and easier-to-use system. - GA

This is how the first 100 complete units will look. After then it 10mm lower.

yohan,

they look really nice and if they hash as much as they're nice we're ok! Smiley

It's the best looking fpga of the market, I cannot wait to get mine.

Lets hope performance reach 800Mh/s
